Think you can hold a grudge? Crows can hold one for 17 years

Are you the type who quickly forgives and forgets? Or do you still carry a burning sense of anger over small things that happened decades ago? If it is the latter, you may have something in common with crows.

The birds can harbour a grudge for as long as 17 years against those who upset or threaten them, a scientist has found.

If you ever find yourself dive-bombed or aggressively cawed at by a crow, you must ask yourself: did you do anything to upset that particular bird — or any of its friends or relatives — over the past two decades?

I'm still pissed at CBS for limiting Ron Paul to 89 seconds of time in a 1 hour "debate" back in Nov 2011. Does that count?

I still hate kids from high school, and a lot of them have died....

It's nothing to crow about...

I always wondered how a group of crows got named “a murder.”

I've got crows beat. I never forget and I never forgive. Life is simpler that way.
